i hope this kind of post is alright. i'm always unsure of what to do on forum-like sites. here's a few songs that i tend to listen to to help either calm me down and get me in a better mood or to help me sleep. been listening to these for the past two years or longer and they tend to help a lot. i hope any of them helps someone else. not all the same genre so someone should be able to find at least one they like.
not all of these songs are soft and quiet but they're all pretty good.

other ones that aren't meant for calming but are more so relatable and you might listen to them to express yourself. definitely helps me release things when i can't talk to my bud or might be crying about something at the time.
Lower Than Atlantis - Words Don't Come so Easily (has to do with not being able to speak well. i really relate to it when i'm having social issues.)
Lower Than Atlantis - Had Enough (this is one a rebellious, angry teenager would listen to when upset. it's pretty loud and brash.)
The Lumineers - Sleep on the Floor (relates to the feeling of wanting to get away at least for a moment)
Jeremy Zucker - All The Kids Are Depressed (title's pretty self explanatory)
Prelow - I Don't Wanna End The Night
Prelow - Backseat
Mother Mother - Body (dysphoria and self image issues)
